trouble building bgl-viz
by VP of Communciations 23 Jan '06

23 Jan '06

I have successfully installed boost with VC express (windows), but am having trouble getting the DOT reader going. I don't seem to have the bgl-viz library. I have followed the directions on the "getting started" page and the read_graphviz page, but I must be doing something wrong, because I am not getting the bgl-viz library. I'm new to boost and C++, so please forgive me if these are elementary questions. How do I build the bgl-viz library? Thanks.

graph compile error with gcc3.3 when edge container is slist
by Weiqing Guo 23 Jan '06

23 Jan '06

Hi, the attached source code is copied from boost_1_33_0/libs/graph/example/adjacency_list.cpp, I only changed the edge container to be slist, and include <slist.h> I compiled it on linux with AMD opteron 844 processor. gcc2.95.3 works fine, but gcc3.3 doesn't compile. I think the reason is slist is not in std namespace in gcc3.3, and adjacency_list.hpp doesn't handle this correctly for slist. > grep BOOST_STD_EXTENSION_NAMESPACE adjacency_list.hpp adjacency_list.hpp: typedef BOOST_STD_EXTENSION_NAMESPACE::slist<ValueType> type; adjacency_list.hpp: typedef BOOST_STD_EXTENSION_NAMESPACE::hash_set<ValueType> type; adjacency_list.hpp: typedef BOOST_STD_EXTENSION_NAMESPACE::hash_set<ValueType> type; adjacency_list.hpp: struct bind_ { typedef BOOST_STD_EXTENSION_NAMESPACE::hash_set<T, std::less<T> > type; }; adjacency_list.hpp: struct bind_ { typedef BOOST_STD_EXTENSION_NAMESPACE::hash_set<T, std::less<T> > type; }; should slist be handled the same way as hash_set ? thanks weiqing //======================================================================= // Copyright 1997, 1998, 1999, 2000 University of Notre Dame. // Authors: Andrew Lumsdaine, Lie-Quan Lee, Jeremy G.

Signature of files saved by boost::serialization
by Bo Peng 23 Jan '06

23 Jan '06

Dear list, What would be a good way to tell if a file is saved by boost::serialization? I notice that the first several characters of binary_oarchive saved files are "\026 \0 \0 \0 \0 \0 \0 serialization" and are "22 serialization" for text_oarchive saved files. Are they reliable signatures? Many thanks in advance. Bo

Weird cross compiling issue
by James Hughes 23 Jan '06

23 Jan '06

Hello all, I am cross compiling Boost to an embedded Linux Arm architecture. I reported a problem a week or so ago with failures in some of the libraries which I was unable to solve, and have a bit more information. One of the issues appears with the serialisation library. Although I am compiling for Arm, the serialisation libs end up as Intel X86 binaries, even though all the other successfully compiled libs are ARM. This then leads to problems elsewhere with libraries that appear to need the serialisation libs. I can only think that there is an issue with the make system to do with serialisation area. Anyone have any comments/thoughts? In addition, when I do a build to a particular directory: bjam "-sGCC_ROOT_DIRECTORY=/opt/montavista/mobilinux/devkit/arm/iwmmxt_le" "-sGCC=iwmmxt_le-gcc" "-sGXX=iwmmxt_le-g++" stage the stage folder is created, in which is a lib folder, in which are all the binaries (including the defective Intel ones). However, I would also expect some header files somewhere - should there also be a h (or header) folder next to lib? If not where are the headers I need to include in my apps using Boost?

Version Mgmt classes/algorithms
by Rich Johnson 23 Jan '06

23 Jan '06

Today 09:06:47 am Hi folks-- I'm looking for a peer-reviewed solutions for managing versions (dll compatibiity, data formats, etc.). If they exist, they're pretty hard to find. ( FWIW, searches with the terms "version" or "versioning" aren't very helpful :-() To date all I've been able to find are ad hoc discussions on matching a specific version. Ultimately, I _think_ I'm looking for 1) a base class for a version specification 2) a range for version compatibility 3)a mixin class (with compatibility check methods) for objects requiring version compatibility. The two use cases I have in mind are: 1) - an application wishes to verify compatibility of a dlopen()'d module as well as the compatibility of its separately compiled objects. 2) - a decoder wishes to verify compatibility with a data file being decoded. Have there been any discussions on this topic in the boost domain? If so, how would I find it? Any one have ideas where else I could look? Or any useful codewords to search for. Thnx --rich

newby problem: boost build problems under debian
by Grégoire Weber 23 Jan '06

23 Jan '06

Hi! I try to build boost from source (boost-1.33.1 from sf.net) under debian stable on x86. In the first run I followed the "Getting Started" document but run into problems. In a second round I tried out the following additionaly: * I downloaded and extracted the sources (tar) to my BOOST_ROOT * I built bjam according the "Building Boost.Jam" instructions: http://www.boost.org/tools/build/jam_src/index.html#building_bjam --> bjam seems ok to me * In Step 4 before carrying out the install uncommented the ``using gcc ;`` line in BOOST_ROOT/tools/build/v2/user-config.jam * Step 5: In the BOOST_ROOT I tried to trigger install``bjam --v2 install`` Now I'm stuck here, googling around didn't help. Any hints? Thanks. Gregoire P.S.: Everything I do I do as ordinary user.

boost::serialization stream exception
by Adrian Grigore 23 Jan '06

23 Jan '06

Hi, I encountered a mysterious stream exception when trying to deserialize an std::map<std::string,long> container. The exception seems to occur depending on the data stored in the container. Unfortunately none of the hints regarding stream exceptions from the manual seem to help. The source code is as follows: >>>> std::map<RHANDLE,long> ArchiveEntries; ... void ResArchive::SaveToFile() { std::ofstream ofs (INDEX_FILE_NAME); boost::archive::binary_oarchive OArchive(ofs); OArchive <<ArchiveEntries; } void ResArchive::LoadFromFile() { std::ifstream ifs(INDEX_FILE_NAME); boost::archive::binary_iarchive IArchive(ifs); IArchive >>ArchiveEntries; //STREAM EXCEPTION!!! } <<<< I do not open any file stream to the index file in any other part of my source code, so multiple simultaneous streams can't be the problem. I can consistently reproduce the error for 2 given sets of test data, but I also have some test data ( just 2 entries instead of a few thousand) where the problem does not occur. I have not been able to isolate the exact data that is needed to cause such a stream exception though. Any hints on how to proceed would be greatly appreciated. Thanks in advance for your time! :-) Best Regards, -- Adrian Grigore -- Adrian Grigore adrian(a)lobstersoft.com Lobstersoft - Fun Brain-Bending Games For All Ages http://www.lobstersoft.com Member of the Association of Shareware Professionals

[Nat] Um, no. But since .vcproj files are specially-formatted text files, I assume the worst case would involve building a new static-library project by manually setting things the same way in your new project file as in my old one.
